'65 Brake Shoe Guide Plates?

My question is were these things used in/on '65s? this is the odd shaped plate that is used on some Ford products I've seen that kind of holds the brake shoes together at the top-slips over the anchor pin before the 2 springs go on.Thanks!

OK, I believe I've answered my own question: I do not believe that the '65-'66 Mustangs use this plate as there is no "step-up" on the guide pin for this plate nor is there any room for it to fit there with the springs installed.

I do have anouther spring question: (its been a while since I've replaced brake shoes on an early Mustang or any other car for that matter)(and I'm starting from scratch with a restored rear end) I need to know which spring is the primary and what spring is the secondary-they look alike but 1 is obviously hevier? and I can't tell from the pictures I have which one is which.

Yes, It does!! Thanks!
